TAKE-UP MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 390,630, dated October2, 1888.

Application filed February 13, 18i-8. Serial No. 263,982. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM P. UHLINGER, a citizen of the United States,and a resident'of Philadelphia, in the county of Philadelphia and Stateof Pennsylvania, have invented certain new and useful Improvements inTake-Up Mechanism for Looms; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to whichit appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked thereon, which form a part of thisspecification.

Figure 1 of the drawings isaside elevation v of part of a loom, showingmy improved takeup and compensator; and Fig. 2 is a view of part of thesame, on a somewhat enlarged scale.

This invention has relation to looms, and refers especially to certainimprovements in the take-up motion and compensating devices connectedtherewith, all as hereinafter set forth.

The improvements are particularly designed for use in connection withribbon-looms, although they may be employed in other looms, if desired.The fine and exact character required in the work of ribbon-loomsrenders the invention of comparatively greater importance in this classof weaving-machines.

Referring to the accompanying drawings, illustrating this invention, theletter A designates the frame-work of the loom, and B the breast-beamthereof, having the guide a for the work 0.

G is the lathe, and D represents the shuttle in position.

E is the lathe-arm, having a pendant, G, which is connected to the crankand fly-wheel F by the rod 0. In rear of this crank and fiy-wheel is therocking-lever H, which is pivoted in the frame and stands in an uprightposition. This lever is provided with slides d d, which may be securedin any adjusted position by means of set-screws d", and to which areconnected the ends of the cords or connections e e, of which one extendsto the lathe and the other passes over the guideroller f and isconnected to the link 9, thereby transmitting reciprocatory motion tothe said link. By means of the slides d d the feed can be adjusted tothe number of picks to the inch required in the work.

The take-up rolls V are keyed on the shaft \V by set-screws n, so thatthey will turn with said shaft, which is pivoted in bearings of theframe and is provided with a gear-wheel, J, the diameter of whichisabout equal to the full diameter of the roll and the work woundthereon. By intermediate gearing, J J, as indicated, this wheel J is putin connection with a cog-wheel, J, on the shaft R, which carries thefriction-wheel I, which is preferably made of wooden sections k 70,having the grain of the wood extending radially. The outer curvedsurface of the friction-wheel is a true cylinder.

On the shaft R is keyed a take-up lever, I, which is usually made withtwo arms, 1 and in, one below the other and parallel to each other. Theupper arm, Z, carries pivoted thereto the friction-pawl K, which is ofsector shape, its curved end having, however, a slight eccentricity, sothat it will have'a purchase upon the friction-wheel I, in connectionwith which it is designed to operate. On'the lower arm, m, is a movablesleeve or slide, S, to which is pivoted a link, 9, to which the end ofthe cord or connection e is attached, and to which is also pivoted theforward end of the connection a, the rear end of which is pivoted to theswinging arm Z, which is keyed on the shaft M.

L is a holding-pawl of similar character to the pawl K, and pivoted tothe loomframe in rear of the friction-wheel, as indicated. A spring, s,holds the pawl L to the work.

A compensating pressure-lever, P, is also keyed to the shaft M and isprovided with a pivoted head, IV,which bears on the work as it is woundon the roll V. The lower end of the lever curves or extends forward andis provided with a weight, w, which may be, in order to render itadjustable, furnished with a bail or loop adapted to engage one of aseries of notches in the upper edge of the lever.

In this take-up the friction-roll is designed to be turned while thelathe is moving forward to beat up and the warp is closing, so thatthere is no appreciable strain on the work. As the winding increasesupon the rolls V, the pressure-head moves outward and the pressure-lever1? turns the shaft M, and thereby swings the arm Z forward. Thismovement pushes forward the sleeve S on the arm in of the lever I towardthe end of'said arm, so that the circular motion communicated to thelever I by the lathe through the medium of the rocking lever H and cordsc 6' will be gradually decreased. In this manner the feed of thefriction-wheel I, and consequently the circular movementof the roll V,will be gradually and proportionately decreased, as the winding on saidroll increases, and a steady and uniform takeup of theproper number ofpicks to the inch will be preserved as the work is being wound up whilethe weaving process is going on.

To obviate undue wear, the curved ends of the pawls K and L may hecovered with thin rubber.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s-

1. In a loom,the combination with the lathe and takenp roll, of thecompensating pressnrelever P on the shaft M, provided with a pivotedhead and moved by the cloth winding on said roll, the weight, thefriction-wheel I,

consisting of the sections 70, the pawls K L, the swinging arm Z, keyedon the shaft M, the take-up lever I", having the parallelarms, themovable sleeve on the lower arm, the connections it and e 0', the leverH, and the gearing J J J J, substantially as specified.

2. In a loom, the combinatiomwith thelathe and take-up roll, the rockinglever H, provided with the adjustable slides, the set-screws d, andcords e e',0f the compensating pressurelever 1?, having the pivotedhead, the Weight, the arm Z, the shaft M, the connection n, thefriction-wheel I, the pawl L, pivoted to the frame, the holding-spring,the take-up lever, having parallel arms, the upper arm of said leverhaving the sector-shaped pawl, the slide on the lower arm, the link andthe gearing J 'J J J substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM P. UHLINGER.
